WebJul 30, 2024 · Here we will see how we can check number of set bits in an integer number. The set bits are 1’s in the binary representation of a number. For an example the number 13 has three set bits 1101. So the count will be 3. To solve this problem, we will shift the number to the right, and if the LSb is 1, then increase count.
